Description

The si920 is a high-speed optical sensing interrogator, capable of monitoring vibration modes using FBG sensors on up to four simultaneous channels with acquisition rates as fast as 500 kHz on a single channel or 100 kHz on four parallel channels. The si920 is built with a unique, patented architecture, using parallel high performance Fiber Fabry-Perot tunable filters. The unmatched optical performance of Micron Optics' tunable filters ensures high speed, high sensitivity sensor vibration measurements from the si920 that are unparalleled in the industry.

High speed optical sensor and vibration measurements using the si920 can be used in applications such as ballistics testing and blast analysis, acoustic emissions monitoring, and other high speed vibration mode analysis applications.
